REPAIR-LAST.

Specification of Letters Patent.

Patented Feb. 10,1914.

Application filed September 12, 1912. Serial No. 719,902.

To all whom it may concern Be it known that I, DANIEL RoUNns, a citizenof the United States, residing at Portland, in the county of Cumberlandand State of Maine, have invented certain new and useful Improvements inRepair-Lasts, of which the following is a specification.

This invention relates to improvements in shoemakers repair lasts and isdesigned to provide a simple laterally and longitudinally adjustablelast.

In the drawings herewith accompanying and making a part of thisapplication, Figure 1 is an elevation with a portion of the side removedof my improved last; Fig. 2 is a top plan with a portion of the topremoved of the same; and Fig. 3 is a detail of the laterally expandingdevice.

In said drawings A is the heel part and B the toe part. Pivotallymounted in the heel part is a block C provided with a longitudinal barreceiving opening D. Mounted in the toe part is a bloc: E provided witha longitudinally extending bar receiving opening F. The block C ismounted on a pivot bar G and the block E may be adjustably held in placeby means of a threaded bolt H passing down through a slot 1 in anextension J 01": the block E and threaded in the bottom of the last.Mounted in the openings in blocks G and E and extending between the twoparts of the last is a bar K. Set astride said bar K is an invertedU-shaped coupling L. The two parts of the last or the blocks in whichthe bar K is mounted are connected by toggle links M on one or bothsides thereof, the opposite ends being pivotally secured in the heelpart and forepart respectively and the adjacent ends being pivotallysecured to the coupling L. A threaded post N passes through a threadedopening in the top of the coupling and is stepped in the top of the barand has a wrench receiving terminal 0, whereby the turning of post Ncauses the coupling to rise or fall and the toggle links to contract orexpand according as the post is turned.

The forepart of the last is divided longitudinally and each partprovided with one or more laterally extending holes P in which aremounted sustaining bars Q which extend across the line of division andserve to keep the two parts in proper vertical alinement. In theiorepart of the last is mounted an expanding device comprising togglelinks It provided at the inner extremity with holes S through whichproject vertical posts T set in the bottom oi the last, one on each sidethereof. The toggle links comprise two pairs which are connected bycouplings U and 3V respectively. The conplings are provided with anoperative post V terminating in a wrench receiving terminal V. The partX of post V on which the coupling W" is mounted is threaded in onedirection and the part X on which the coupling U is mounted is threadedin the opposite direction.

4 The operation of my improved repair last is as follows: To insert thelast in the shoe, it is brought into the smallest compass, bothlongitudinally and laterally and then inserted in the shoe. The wrenchis then applied to the vertical post N, the turning of which causes theU-shaped coupling to descend over the bar K carrying with it theadjacent ends of the toggle links, thus forcing the two parts of thelast apart until the shoe is filled longitudinally. The wrench is thenapplied to the post of the expanding device and turned until thetorepart is expanded to completely fill the shoe laterally. To removethe last from the shoe the operation is reversed, contracting the lastboth longitudinally and laterally. V

The advantages of my improved last are simplicity of construction andoperation, durability and adjustability, whereby the last is caused toit the shoe both longitudinally and laterally.

Having thus described my invention and its use, I claim:

In a repair last, a toe part and heel part, a block mounted in the heelpart and provided with a longitudinally positioned bar receivingopening, a block mounted in the forepart and provided with a similarlongijacent ends pivotally attached to said U- tudinally positioned barreceiving opening, shaped coupling, and means for imparting 10 a barslidably mounted in said blocks, a U- vertical movement to saidcoupling.

sha ed con lin set astride said bar and vertically in dval le relativeto and in contact DANIEL ROUNDS' with said bar, toggle links havingtheir relVitnesses:
